COIL MOUNTING.

Application filed July 20, 1925. Serial No, 44,801.

This invention relates to mountings for coils and more particularly for coils of the spider web type used in radio communication.

The invention is fully described in the following specification and shown in the accompanying drawings in which:

Figure 1 is a top plan view of a coil and mounting;

Figure 2 is a side elevation of the same;

Figure 8 is a similar view of the mounting showing the coil removed; and

Figure 4 is similar to Fig. 1 with the coil removed.

The embodiment illustrated comprises a spider web coil having primary and secondary windings 10 and 10 of a well-known type which has a series of radial openings 11 of diamond shape cross section separated by crossed wires 12.

The mounting therefor consists of a base 18 having two projecting tapered pins 1 1 and 15 which are so formed so as to fit snugly into two adjacent radial openings 11.

The base 16 on the pin 14. and the base 17 on the pin 15 are substantially parallel, but are separated by amounts sufficiently equal to the thickness of the insulated wire of which the coil is composed. This is also true of the faces 18 and 19.

Thus the tapered pins which are tapered slightly more than the openings in which they are adapted to fit, fit snugly into these openings and are adapted to be wedged therein, thereby similarly supporting the coil.

If desired, an insulating cement may be used for securing the coil on the mounting. This same cement is also commonly used for dipping the entire coil to render it self-supporting.

The base 18 is secured to a bottom panel or the like 20 by means of four screws 21, 22. 23 and 24 with a metal connector 25 held under the head of each. If the coil 10 has only a single winding the two ends of this coil may be soldered to two of the connectors 25. If, however, the coil is a radio frequency transformer having primary and secondary coils, the ends of the primary may be soldered to two of the connectors :25, while the ends of the secondary are soldered to the other two connectors. Similar connectors 26 are placed beneath the nuts on the underside of the panel 20. Thus, a convenient method is provided for mounting and connecting the ends of the transformer coils.

It will be not-ed that thismounting adapts itself to coils of different diameter both externally and internally over quite a range, so long as the number and size of openings remains the same and the pins are made long enough to accommodate the different sized coils.

In the embodiment illustrated, the primary coil 10 is entirely separate from the secondary coil 10 and is supported on the ends of the pins 14 and 15 and upon a pin 27 passing through corresponding openings in these two coils. To avoid confusion the wires leading from the ends of these coils to the terminal screws 21, 22, 23 and 24 have been omitted.

While I have shown and described but a single embodiment of this invention, it is to be understood that it is capable of many modifications. Changes therefore in the constructions and arrangementmay be made which do not depart from the spirit and scope of the invention as disclosed in the appended claims.

I claim:

1. A mounting for spiderweb coils having radial openings, comprising a base having tapered pins of diamond-shaped cross-section projecting therefrom adapted to be inserted into said radial openings.

2. A mounting for spiderweb coils having radial openings, comprising a base having tapered pins of diamond-shaped cross-section projecting therefrom adapted to be inserted into said radial openings, the adjacent edges of said pins being substantially parallel.

3. A mounting for spiderweb coils having radial openings, comprising a base having tapered pins of diamond-shaped cross-section projecting therefrom adapted to be inserted ill into said radial openings, said openings being diamond shaped and separated by crossed wires of the coil, and said pins being adapted to snugly fit into substantially all parts of said openings.

at. A mounting for spideiweb coils havino; diamond. shaped i'adial openings, and a base having a diamond shaped pin projecting therefrom adapted to fit snugly into one of said diamond shaped openings to retain the coil thereon.

5. The combination of the mounting and coil of claim 1, and an adhesive means for securing them together.

6. The combination of the mounting and coil of claim 4, and an adhesive means for securing them together.
